> There is a relationship between MasterJob--->MasterJobAux where i checked "To
> Dep PK" since no ARTIST_AUX rows can exists without corresponding MasterJob.
> When i fetch a MasterJob i have added a prefetch for MasterJobAux :
> query.addPrefetch(MasterJob.RELATED_MASTER_JOB_AUX_PROPERTY);
> Code I use to get/create/delete MasterJobAux
> protected MasterJobAux createAux(ILookupFieldCodes fieldCode,
> Short seqNo, String value) {
> MasterJobAux aux =
> MasterJob.this.getObjectContext().newObject(MasterJobAux.class);
> aux.setScheduleId(MasterJob.this.getScheduleId());
> aux.setJobName(MasterJob.this.getJobName());
>
> aux.setJaFieldCode((int) fieldCode.getID());
> aux.setJaSequenceNumber(seqNo);
> aux.setJavalue(value);
> aux.setRelatedMasterJob(MasterJob.this);
> return aux;
> }
> protected List<MasterJobAux> fetchAuxList() throws
> OpconException {
> return MasterJob.this.getRelatedMasterJobAux();
> }
> protected void deleteAux(MasterJobAux toDelete) throws
> OpconException {
> MasterJob.this.removeFromRelatedMasterJobAux(toDelete);
>
> MasterJob.this.getObjectContext().deleteObject(toDelete);
> }

> To reproduce the problem :
> 1) Fetch MasterJobAux using the relationships
> MasterJob.getRelatedMasterJobAux();
> 2) delete/create some MasterJobAux
> MasterJob.removeFromRelatedMasterJobAux(toDelete);
> MasterJob.getObjectContext().deleteObject(toDelete);
> 3) Rollback
> 4) re-Fetch MasterJobAux using the relationships
> MasterJob.getRelatedMasterJobAux();
> I get TRANSIENT objects, you can look a the SQL log attached where there is
> some others details.
> Thanks.
